Title: APC Prop on a Fox .35
Post by: John Leidle on November 18, 2020, 04:48:19 PM

  I pulled out my Sheeks Grumman Skyrocket today & it has a pair of Fox .35s for power. It also can use nose weight So I wonder if an APC prop is ok to use reason I ask is in the past guys have snapped the crank shaft using such a heavy prop maybe they used a modified Fox I'm not sure.
   If I was smart I'd most likely stuff a pair of Thunder Tiger .36s in it....
    Any advise , info is welcome...

   Probably an overblown issue *as long as you don't use too much nitro*.

  Ha, ha , ha ,   I guess I only have 10% nitro on hand with the castor required so I probably will be ok nitro wise but I know that you know me so thanks for the reminder .
   I really am anxious to try this thing out ...

John,
I have had good luck with both 10x4 and 10x5 APCs on different Foxes and airframes for stunters.  The APC 9X6 has been good for faster applications such as Foxberg racers.  Also it is my opinion that the APC props seem to smooth the run out.
Good luck,
John
